i'm using p4 3.2 ht pc with 875pbz motherboard. it's temp is too high.
tell me some good way to cool down it.
Install more fans or you could even go for a liquid cooling system

Maybe there is too much dust inside the case that the heatsink can't dissipate the heat properly.
You need good ventilation inside the case. But it doesn't mean you need half a dozen fans in it. Ideally, you need one or two front intake fan and one or two exhaust fans. Air need to come into the case at the same speed (or volume) as it goes out. Otherwise pressure will build up inside the case and this will increase the temperatures. (BTW, I have one exhaust fan + the fan in the power supply unit, and not a single intake fan. Not only that; the exhaust fan is working with only 7V instead of the 12V so it's running slower than default. CPU fan only runs at 900rpm!!! Yeah, you read it right :yes: After all this, my CPU is about 10-15 degrees cooler than my hard drive!!! But this is a Core 2 Duo ;))
Anyways...
Maybe you would want to take out the CPU heatsink and clean it up. You will have to clean the contact surfaces of both the heat sink and the CPU heat spreader. I used to wipe it with a tissue paper and polish it with a new tissue paper so that there aren't any residue. But when fitting the heatsink back, you have to apply some fresh (clean) thermal paste. You will have to buy some off a PC shop. So, before removing the heatsink, make sure you have some thermal paste lying next to you. There are very good thermal pastes, but in Sri Lanka, I doubt you will be able to find any good ones (such as Arctic Silver 5). Nevertheless, you HAVE to apply thermal paste, even it's junk, otherwise the CPU might fry eventually because of bad contact between the heat sink and the CPU heat spreader.

hey Anusha ur damn right man. My pc is 3.0Ghz with old 915GEV mother board. And its also heated 65C or up ( when 100% CUP useage ). So i install three sucking in fans ( side bottom of the cassing ) and two sucking out fans ( one is mount top of the casing and one is mount back side ) so now its heated 50c to up ( when 100% CUP useage ).

Remove the processor & the mother board & keep it on the refrigerator for half & hour. :oo::oo::oo::oo::oo:

If it's a Prescott CPU, 70C at full load is not something to worry about (on stock cooler that comes with the CPU).

Prescotts are the ones that has 1MB or more L2 cache.
If the PC is stable, then don't worry much about it. I don't think you are gonna use that PC for 10 years, so I don't think 70C will kill it. Also see if it's really that hot by touching the heatsink. It could be that the thermal sensor if reading a wrong value.
My cousing has a Prescott 3GHz CPU and even after I replaced his stock cooler with a Gigabyte heatpipe cooler (can't remember the name, damn!), stil the temperatures were reaching mid 70s. I wouldn't worry that much about it if your system is rock solid (means no random crashes or reboots).

i think itz normal for that processor. Anyway get a good heatsink which mostly done in copper. good fan will help too.
I think Coolmax, Cooler master, Thermaltake has better heatsinks and combo processor coolers too.

I dont think this sucking in fans r a good idea. It suck all the dust in and u have 3 of them:shocked: . I also hav a 3GHz HT pc with 2 fans( front and back - one controlled by software I guess). My pc's max temp is about 45C:yes: of course the room is airconditioned;) :lol: :lol: :lol:

No dude, those two fans(top & back side fans) are blowing air out of the case(coz hot air rises). & he got 3 fans in the bottom of the casing to get the air in... :yes:
......
& of course the intel 6xx series gets a bit hot :rolleyes: & the stock hsf isnt the best :no:

I think two or three exhaust and intake fans would do. I hv 2.8 with intel 915. the system overheated every few minutes. i installed two fans and the problem is solved.
until you buy a fan, you may keep your casing open. will reduce the temp.

air intake fans are good. but don't install them if your machine is not in a a/c room. otherwise dust will make your pc dead.
and another one thing...
please don't open casing and turn on... it will not reduce the temp. casing is designed to make a good air circulation inside it...

I don't agree with you. Even if you have zero case fans, the case still sucks dust in. Why? Because the power supply unit's exhaust fan makes a vacuum effect and from the vents in the front and sides of the case, cool air comes in. Hell, even with only on exhaust fan running at 7V instead of 12V and the power supply unit's two fans, I still feel cool air being sucked in when I put my hand close to the vents. Dust comes in regardless of whether you have intake fans or not. And remember, dust is not dangerous as excessive heat. Heat should be given the priority. Besides, you can clean inside of your case every one month or three months. You can't do something like that about the heat. And remember, dust can't do much harm to the circuit boards because, the circuit routes are covered with a glossy coating and most boards have internal connections (as most of them have several layers). But one thing to remember is that you should not let dust deposit on heatsinks, because then, it will make it less and less efficient in dissipating the heat out.

Not every casing is designed to make a good air circulation, especially the ones we find in Sri Lanka - the no-name brands or the unpopular brands. The pioneers in case design have good designs - yes.
Anyway, you have to have a good cable management inside the case such that the cables - IDE cables more specifically - do not block the path of the air. Try to keep them directly out of the air flow of the intake fans.
Opening up the case might help in the short run, but I also don't recommend that. If you have to keep your case open to make it work, it means something is seriously wrong with your system. Address that issue properly.

Anusha yes machan. When they designed motherboard and other cards they assume users have good Air circulate cassing. Some users worry about only processor temp. But that is damn wrong.
Anusha

And also, keep enough space between hot parts.
Examples:
1. leave at least one bay free between hard drives (if you have more than one).
2. Don't install an expansion card next to the video card(s). Video cards usually run hotter than anything else, so leave enough room around them for enough air to absorb the heat.
3. Use a power supply that has an intake fan right on top of the CPU. Normal power supplies only have the exhaust fan at the rear and it uses the vacuum effect to get the hot air into it and out of the case. Forced intake would better remove the hot air around the CPU.

My room is not air con. i installd one itake and one exhaust. but it doed not seem to attracting too much dust. there are some dust on the fan blades. but not very badly.
I mean till you buy sm fans. opening case does not solve the case completely. for short run it will serve.
